Chromium(III) phosphate can exist as two isomorphs. Its β-isoform is orthorhombic with the Cmcm space group (a = 0.5165, b = 0.7750, c = 0.6131 nm). The structure consists of infinite chains of trans edge-sharing CrO6 octahedra, which run parallel to the c-axis, and are linked by PO4 tetrahedra. Above 1175 °C, β-CrPO4 converts to α-CrPO4. α-CrPO4 is orthorhombic as well, with the Imma space group (a = 1.0380, b = 1.2845, c = 0.6278 nm).
